x86: fix warning in arch/x86/kernel/microcode_amd.c
this warning:
arch/x86/kernel/microcode_amd.c: In function ‘apply_microcode_amd’:
arch/x86/kernel/microcode_amd.c:163: warning: cast from pointer to integer of different size
arch/x86/kernel/microcode_amd.c:163: warning: cast from pointer to integer of different size
triggers because we want to pass the address to the microcode MSR,
which is 64-bit even on 32-bit. Cast it explicitly to express this.
